Risks and Opportunities


TANESCO receives a trend score of -. If the company were reassessed in the near future, its score would likely decrease. TANESCO’s emissions intensity is expected to decrease significantly in 2024 and, as a result, the company is projected to remain within its carbon budget for the period 2022-2037. However, the company has not set any emissions reduction targets or created a transition plan. Without these accountability mechanisms and planning in place, there is no guarantee that the company will continue on its 1.5°C pathway.
