As the race to net zero emissions intensifies, one question looms: how will we pay for it? Global investment in climate solutions needs to jump from $900 billion in 2020 to a staggering $5 trillion annually by 2030, according to the International Monetary Fund (IMF). The real estate sector alone faces a $1.7 trillion-per-year price tag to decarbonize buildings and infrastructure. Industries across the globe are seeking new ways to mobilize these massive amounts of capital needed for the net-zero transition. To close this funding gap, voluntary carbon markets (VCMs) offer a flexible, fast-moving financial tool to mobilize private capital, reduce emissions, and unlock innovation in carbon-intensive industries like real estate.
