Our planet's ecosystems are declining, and immediate efforts to restore them are essential. Even in cities, we need effective solutions for conserving the environment through Nature-Based Solutions (NbS).

• NbS: Using the function of nature to solve social issues
• Projects for conserving diverse ecosystems from mountains to coastlines

• Addressing local needs to achieve SDGs with effective solutions
• Managing of suburban hillsides: controlling runoff, conserving forests for CO2 absorption, and mitigating climate change
• Conserving coastal ecosystems: preventing disasters (e.g. storm surges/tsunamis, controlling erosion, enhancing water quality

• The Project for Community-Based Sustainable Natural Resource Management (CBNRM) Phase II, Timor-Leste (JICA, 2016-2022)
• The Project for Biodiversity Conservation through Implementation of the PNG Policy on Protected Areas, Papua New Guinea (JICA, 2015-2021)

Demand from investors to private companies to adopt decarbonization measures, making carbon credits and decarbonization activities urgent priorities

Currently private company has been facing climate change challenges, such as :

• Supporting services of JCM model project (subsidy scheme) application
• Preparation service of Project Design Document (PDD)
• Development of GHG calculation methodology under JCM scheme
• Implementation of feasibility study on JCM project
• Networking of JCM project development

Recently, the wave of demand for a decarbonized society has spread from the central government to local governments and private companies, and countermeasures have become an urgent challenge.

By providing this support, it will be possible to build a system for implementing decarbonization solutions in both soft and hard aspects in the region

• Empowering of decarbonization solutions: Local governments & private companies unite via JCM mechanism (See following figure)
• Building decarbonization platform/network

Since 2013, Nippon Koei‘s International Environment Dept. has initiated city-to-city collaborations with Japanese/foreign cities and private companies including the following.
