GPP

GPP is an acronym used in multiple fields, referring to different concepts depending on the context.

In ecology, Gross Primary Production denotes the total carbon fixed by photosynthesis in an ecosystem before plant respiration. It serves as a benchmark for ecosystem productivity and carbon uptake, with values typically higher in more productive biomes. Net Primary Production (NPP) is the GPP minus the carbon used by plants for respiration.

In computing, GPP stands for General Purpose Processor, a CPU or microprocessor designed to handle a wide range of tasks rather than specialized workloads. This contrasts with specialized processors such as digital signal processors (DSPs) or graphics processing units (GPUs), though modern processors may integrate both general and specialized capabilities.

In public policy and procurement, Green Public Procurement refers to the purchase of goods, services, and works with reduced environmental impact throughout their life cycle. The approach aims to promote sustainability, lower energy use and emissions, and minimize waste within governmental and institutional purchasing programs, particularly in the European Union and other regions.

In clinical research, Good Participatory Practice describes guidelines for engaging communities in research trials to ensure ethical engagement, informed consent, transparency, and benefit sharing. GPP emphasizes meaningful involvement of stakeholders and often applies to HIV/AIDS and other public health studies.

Good Publication Practice guidelines, abbreviated GPP, relate to the ethical and transparent reporting of research results. They cover aspects such as authorship, disclosure of conflicts of interest, accurate attribution, and comprehensive acknowledgment of contributors and sponsors.
