One-third of the greenhouse gas reductions needed in the next decade can be achieved through improved nature’s capacity for carbon absorption: protecting and restoring forests, grasslands, and wetlands. This solution category currently receives only 3% of global climate funding. That gap represents one of the clearest misallocations in climate action today.
Understanding why the gap exists, and what businesses and individuals can do within it, is more useful than a general list of sustainability tips.
The Two Tracks of Climate Action
Scientists and policymakers generally distinguish two approaches to climate change: mitigation (reducing emissions and removing atmospheric carbon) and adaptation (preparing communities and systems to cope with the effects already in motion).
Both are necessary, and neither can substitute for the other. Mitigation investments without adaptation investments leave communities vulnerable to the effects already locked in by historical emissions. Adaptation investments without mitigation investments address symptoms while the underlying problem continues to worsen.
For businesses, this distinction has practical implications. Reducing supply chain emissions is mitigation. Building supply chain resilience against drought-driven crop failures or flood-damaged logistics infrastructure is adaptation. Most corporate sustainability programs focus almost exclusively on mitigation; the adaptation dimension is typically absent from ESG reporting.
What’s Actually Moving the Numbers
The electricity system is the most important near-term climate variable. Globally, electric power generation is the largest single source of greenhouse gas emissions. The cost of solar and wind has fallen 90% and 70% respectively over the past decade, making renewable electricity the cheapest energy option in most markets. The transition is underway, but its speed depends on policy, infrastructure investment, and financing access.
Transportation is the second-largest emissions category in the US, and electrification of both personal vehicles and freight is accelerating. Electric vehicles produced fewer lifecycle emissions than conventional vehicles in 2022, even accounting for grid emissions, in virtually every country where data is available.
Buildings represent the third major opportunity, through efficiency retrofitting and heat pump conversion. These investments pay back in energy cost savings while reducing emissions: the same alignment between environmental and financial return that characterizes the most durable sustainability investments.
The businesses that will be positioned well in 2030 aren’t the ones with the best sustainability marketing today. They’re the ones that have reduced their energy costs, built resilient supply chains, and invested in the technologies that are becoming dominant.
What Earth Day and Environmental Campaigns Actually Accomplish
Earth Day generates awareness and gives organizations a communications platform. That matters for long-term culture change, though it’s hard to measure. What Earth Day doesn’t do is directly reduce emissions, change policy, or move capital.
The most impactful business actions in environmental awareness are specific and financial, not general and communicative. Joining the Carbon Disclosure Project and publishing verified emissions data. Partnering with verified reforestation organizations rather than buying generic carbon offsets. Setting science-based emissions reduction targets aligned with IPCC pathways.
Companies can participate in the public policy dimension by supporting climate legislation, advocating for renewable energy infrastructure, and providing technical input on regulations that affect their sector. These actions don’t generate as much social media content as Earth Day campaigns, but they move policy in ways that individual behavior change can’t.
P.S. Before investing in carbon offsets, verify them against the Gold Standard or Verified Carbon Standard, both of which have public project databases that allow you to assess what you’re actually funding before purchasing.
