Over the past decade, decarbonization has become a global rallying cry, giving leaders a common language to tackle climate change by establishing relatively clear, agreed-upon emissions targets. While these efforts have advanced carbon reduction goals globally'though not as fast as everyone had hoped'this singular focus on emissions has led to 'carbon tunnel vision.'1 1 According to the latest Intergovernmental Panel on Climate Change report, for a 50% chance to keep global warming below 1.5 degrees Celsius by 2050, the remaining carbon budget we have available is about 460 gigatons of CO2. If emissions stay at current levels, we will surpass the carbon budget before 2035 (in roughly 11 years). This approach has meant that while companies and industries have ramped up efforts to optimize for net zero emissions, other sustainable development goals and environmental threats have not seen the same momentum. As a result, businesses may overlook the ways in which the earth's climate and natural resources are inextricably intertwined'and miss the opportunity to recognize nature as core to addressing the most pressing environmental challenges.2 2 We define nature as the interaction between human beings and all other living and non-living things, including animals, soil, water, air, forests, ecosystems, and much more. The point is that even well-intended initiatives, including climate action, can harm nature if not managed holistically. With a more holistic approach, companies can deliver a unified strategy that integrates climate action and nature-positive solutions, eliminating the need to track multiple disconnected key performance indicators. (See Exhibit 1.) Leaders across various industries have already embraced this paradigm shift that recognizes the inseparable relationship between nature and climate, and they are aligning their strategies accordingly. Indeed, climate and decarbonization represent just one of the nine planetary boundaries that must be addressed to ensure a safe, just, and sustainable planet for future generations. We are also facing a severe nature crisis including challenges such as biodiversity loss, natural resource scarcity, large-scale environmental degradation, and ecosystem collapse. Many sectors are already feeling the effects'perhaps none more than the global food system . (See Exhibit 2.) The loss of our natural resources affects not only our delicate food system but also our global population. The food system is tightly interlinked with human activity, and the resulting environmental effects of that have cascading socioeconomic impacts, exposing deep-rooted inequalities. To create a truly sustainable future, we must embrace a holistic perspective that ties decarbonization targets with nature-positive ones. (See 'What Are Nature-Positive Targets'') In this article, we address the dangers of carbon tunnel vision, highlight the critical role that a nature-positive approach can play in strengthening the global food system, and offer a set of recommendations to help companies understand how their net zero efforts can also support a nature-positive future. The need to create a sustainable food system while feeding a growing world population is becoming more urgent every year. In the second half of the twentieth century, the green revolution bolstered global food security'and the hard work of farmers around the world has kept us fed through different global crises'but it also massively increased emissions and pushed some natural ecosystems to the brink of collapse . For example, intensive farming practices such as continuous monoculture and agrochemical application have led to deforestation and soil degradation, which in turn increase the risk of erosion and habitat loss. Likewise, the expansion of irrigation systems has depleted water resources in some regions, rendering certain areas unsuitable for agriculture. Given that 75% of food crops 'including vegetables, almonds, and coffee'rely on healthy soil, water, and pollination, continuing along this path has serious implications for the global food system. Pioneers in the food industry , building on decades of research and Indigenous knowledge, provide sparks of hope. But it's clear that we are not moving fast enough. We need to catalyze meaningful change by thinking through a broader range of environmental goals. Some of the shifts needed include: So what can be done to ensure a sustainable future for the food system and protect the planet's natural resources' To achieve widespread benefits, companies must embrace nature-based solutions. More than half the world's total GDP is moderately or highly dependent on nature and what it provides'things many of us have taken for granted, such as clean water, intact forests, and healthy soil. The economic value of biodiversity and healthy ecosystems to society is even greater. Ecosystem services, such as food production, coastal protection, carbon storage, and water filtration, are worth an estimated $150 trillion per year. Failure to care for the ecosystem translates to a significant loss for the sector, up to $25 trillion yearly, endangering the productivity and resilience of the land, farmers' livelihoods, and the food system as a whole. To put it succinctly, nature is critically important to the food value chain. Yet the agriculture industry is the single biggest driver of biodiversity loss . (See Exhibit 3.) The world's land and water resources are being exploited at unprecedented rates. Conventional agricultural systems and supply chains are complex and entrenched, and farmers lack the necessary support to overcome the cost and risk of switching to more sustainable practices. Regenerative agriculture offers an important step forward for the industry. It promotes above- and below-ground carbon sequestration and reduces greenhouse gas emissions, while also protecting biodiversity in and around farms, improving water retention in the soil, improving nutrient use efficiency, and supporting farmers' livelihoods. A recent BCG study in collaboration with One Planet Business for Biodiversity and the World Business Council for Sustainable Development shows that farmers are most likely to adopt regenerative agriculture for two reasons: to reduce costs and to improve soil health. Notably, only 5% of farmers cited carbon sequestration as their primary reason for adopting regenerative agriculture. In other words, a nature-positive solution that improves soil health may be more enticing to farmers than a net zero solution that reduces carbon emissions. The benefits of nature-positive solutions are amplified when stakeholders collaborate and adopt comprehensive strategies at the landscape level (rather than within a single farm). For example, farmers can join forces to protect all local pollinators or collaborate to maintain the integrity of nearby bodies of water. By considering the ways agricultural activities affect the overall ecosystem'as well as local and Indigenous communities'and then managing natural resources in ways that achieve social, economic, and environmental objectives, agricultural communities can build a much more sustainable food system. By implementing landscape-level actions, farmers and companies are also able to engage a broader set of stakeholders, each interested in different areas of focus that can unlock new opportunities for collaboration in areas such as transition finance. Incidentally, numerous other industries can reap the rewards of combining net zero targets with nature-positive ones. (See 'How Pharma Can Benefit from a Nature-Positive Approach.') And there's no time to lose. Whether companies are in the early stages of a sustainability strategy or have already taken bold steps to reduce their carbon footprint, it's time to think bigger by including nature and biodiversity in their plans. Most greenhouse gas emissions and nature loss are a direct result of business-related activities. But this also means that businesses have the power to reverse the damage if they work together. To tackle the challenges in our global food system, an integrated and holistic approach that addresses both climate and nature is critical. Here are several steps companies can take to protect the world's natural resources'the essential assets that enable their businesses to thrive: In its 2023 report, the Intergovernmental Panel on Climate Change said that 'there is a rapidly closing window of opportunity to secure a livable and sustainable future for all.' Increasingly, extreme climate-related weather events have exposed millions of people to acute food and water insecurity'and it will only get worse over time. The climate, nature, and biodiversity crises have reached a point where humanity can no longer afford to watch and wait. To achieve a just and sustainable food system, organizations must assess the most pressing climate and nature challenges within their unique context, identify the areas where they can make the greatest impact, and seize opportunities to act both individually and in collaboration with the larger ecosystem in ways that deliver maximum effect and avoid further damage. We can learn from nature: when an old tree dies in the forest, sunlight reaches places that were previously covered in shade. In these newly illuminated spaces, a burst of new life emerges. A change in context provides opportunities. Companies that prioritize nature, in addition to carbon reduction, can position themselves in the sunlight to emerge as winners in the effort to protect our planet'and become the next generation of sustainability leaders.
